8 Claims. (Cl. 40-458) This invention is concerned with a mounting corner for use in attaching articles such as cards or photographs to album pages, identifying labels to boxes, etc.

A feature of the invention is the provision of a mounting corner having hinged and interlocking parts which may be separated for permitting removal of the mounted article without bending of the latter.

A further feature of the invention is the provision of a mounting corner which can be formed by die-punching and scoring from strip-gummed paper, and assembled by folding and interlocking of parts.

Another feature of the invention is the provision of a mountin corner providing pockets for receiving a corner of a card or other article to be mounted, and with presentation of only a double thickness beneath the mounted article.

A further feature is the provision of a mounting corner which can be used at either the right or left edge of the card, without prior selection, adjustment or arrangement of its structure.

With these and other features in view, an illustrative form of practicing the invention is shown on the accompanying drawings, in which:

Figure l is a view showing four mounting corners in accordance with the illustrative form of the present invention, applied to an album page for holding a picture or card thereto, U

Figure 2 is a layout, on an enlarged scale, showing the position of a number of the mounting corners as blanked from a strip-gummed sheet of paper, and illustrating the several parts of each corner. 1

Figures 3 and 4, respectively, are front and rear views of a folded and assembled mounting corner, on the scale of Figure 2.

Figure 5 is a sectional view substantially on lines 5-5 of Figures 1 and 3, showing the mounting corner applied to a page, with the relative thickness of the material greatly. exaggerated.

Figure 6 is a similar view 5 bstantially on line 6-6 of Figure 1, with a cardin position in the mounting corner.

In the illustrative form of practice, the album page B is illustrated as having a photograph card C fixed thereto by four of the .present mounting corners. These four mounting corners are illustrated in different positions and conditions, in demonstrating the structure and employment of this invention. Mounting corner I shows the general appearance of the. device whenv attached to the base B and receiving 'onecorner of the card C." Mounting'corner'llshow's t e several parts thereof, with the parts which are concealed by the card C being shown in dotted lines to in dicate their relative position behind the card C. Mounting corner III shows the parts of the de vice in the same condition as for corners I and II, but with the corresponding corner of the card C turned back, to show the device as it appears upon the album page B in the absence of the card C. Mounting corner IV shows the device with one of the side wings opened out to permit the lifting and removing of the card without any bending of the latter.

Figure 2 shows the positions of several of the blanks as they may be located in stamping from a sheet of paper. This paper may be stripgummed, and then punched with the successive blanks staggered and overlapping a narrow strip between a pair of gummed strips.

In thus stamping the parts, a glued area I0 is thus provided on each of the blanks, between a first or center tongue II and a folding line I3. In the illustrative form, each center tongue has a pointed end l2. The folding line l3 may be prepared by the usual pressing or scoring, to facilitate accuracy in the folding operation.

The blank is thus formed as an integral structure, with the gummed area 10 and the center tongue II at one side of the folding line [3 and, at the other side, a pair of sidewing portions M, l5 which are separated by a first cut shown as a division slot 16 extending from the free edge to the folding line l3 at a right angle to the latter. Second cuts provide lateral slots ll, l8 which lead from the division slot l6 and have a combined length, from end to end, which is essentially the same as the width of the center tongue I l at the edge 22 of the gummed area thereof. The slots l6, l1, l8 provide the side or second tongues I9, 20 at the terminal of each wing portion remote from the folding line. The edges of the lateral slots l1, l8 which are nearer the folding line 13, preferably diverge from the ends of the slots toward the division slot It, to facilitate the engagement of the center tongue ll during the assembly operation as described hereinafter.

' These corners may be packaged and sold in the flat condition as shown in Figure 2; or they may be folded and interlocked before distribution.

To fold the device into a desirable condition for use, the blank is folded about the line l3 with the gummed area 10 on the outside. The side tongues I9, 20 are then successively flexed and brought around the edge of the center tongue H, into the position of parts shown in Figs. 3, 4

and 5. In Fig. 3, the center tongue ,lloverlies;

portions of the side tongues I9, 20: while other parts of the side Wing portions I 4, IS in turn overlie that portion of the device which bears the remoistening gum on the area I thereof. In Fig. 3, it will be noted that there is no gum beneath the center tongue II, where the same extends above the side tongues I 9, 20, and hence the parts are not connected to one another. In Fig. 4, it will be noted that the gummed area I0 is fully exposed for remoistening, and that when pressed into adhesive relation with the base B, the side tongues I9, 20 are free o be pulled lat erally away from the center tongue I I.

In thus folding the sheet about its folding line l3, the first or center tongue I I with the adjacent g-ummed area It] provides one leaf, and the two wing portions l4, IS with their respective side or second tongues I9, 20 provide another leaf of the folded structure. The wing portions l4, 15, being separated in the illustrated form by the slot 16, are respectively divided by the lateral or branch slots I 1, I 8, so that the side orsecond tongues 19, 20 can respectively be bent out of the plane (see Fig. occupied by the corresponding wing portion at parts adjacent the folding line l3.

When this folding and interlocking has been accomplished, the parts are pressed together and will now sustain one another in the position shown. In Fig. 5, in which the gummed area It is securing the device to the base sheet B, the center tongue ll extends upwardly through the slot l8, and then lies fiat above the side tongue 20. The side wing portion thus has the side tongue located beneath, but disconnected from, the center tongue I I, and for the rest of its structure overlies the portion of the device having the gummed area I0.

When it is desired to employ the device for mounting a photograph on an album page, as indicated in Figs. 1 and '6, a preferred way is to introduce a corner of the picture card 0 into the part of the slot l6 near the fold provided at line 13, and push this corner of the card beneath the adjacent part of the side wing portion, e. g. beneath the side wing portion M of device I in Fig. 1, until one edge of the card is closely within the fold at line l3, while the adjacent edge passes to the end of the lateral slot IT. The 'gum'med area it at the back of device I is then moistened,

and the device and card are located and .pressed into position on the alburn page. Corresponding operations are performed at the other four corners. It will particularly be noted that the card can be inserted either from the right (device I) or from the left (device II) without any prior selection or arrangement of the parts for this purpose.

While it is feasible to remove the card from the four mounting corners by the usual operation of lifting a central portion of the card with a bending of its stock so that the spacial distance between corners of the card is reduced, it is also feasible with the instant device to engage a knife blade or pencil point with the exposed side Wing, and force it laterally away from the engaged edge of the picture card, wherewith its side tongue passes the edge of the card and then the corresponding side wing portion (e. g. wing M of device IV in Fig. 1) can be opened by hingin g about the corresponding part of the fold line I3 into the position shown, therewith removing all constraint from the upper face o thepicture card. When this operation has been performed at two adjacent corners, the card may be slid in its own plane and outof the remaining two-corners. Ob

I side wing and then bending the side wing over the card edge and engaging the side tongue beneath the card and the centertongue H, at each corner which has been opened. Obviously, the corner of Fig. 2 may be secured to a base prior to assembly; and then its side wings folded and engaged with a card to be held.

The corners, for permitting the aforesaid reopening of side wings for card removal, are made of flexible material such as paper of lbs. weight. The paper stock may be decorated or provided with any desired indicia on any portions of its area, such as the exposed areas shown for device II in Fig. 1.

As shown in Figs. 1 and 6, there is a maximum of two layers of the paper stock beneath the card C, so that the device can have the great strength of thick jute or Kraft paper, Without an objectionable number of layers, and, in fact, the device at the corner of the card provides one layer below and one layer above the mounted article.

It is obvious that the invention is not limited to the form of construction shown, but that the same may be employed in many Ways within the scope of the appended claims.
